BAG-LOCK.

Application led February 24, 1921.

To all whom t may cof/worn.' v

Be it known that I, CLARENCE SMITH, a citizen of the United States, residing at Naugatuck, county of New Haven, State of Connecticut, have invented a certain new and useful Improvement in Bag-Looks, or" which the following is a full, clear, and exact description.

My invention relates to improvements in bag locks and has for its object to provide a simple, durable and effective look in 'which the bolt is positively guided by guide-posts so that a desired guiding effect is produced independently of the push-button. A further object 'of my invention is to provide a lock having a. novel means for clogging the bolt.

One feature of my invention is a fourpoint guiding contact between the bolt and the gnideposts. Another feature of my invention is a dog pivoted 'to and moving with the bolt.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which,

Figure 1 shows a front elevation of the lock with the face-plate removed;

Fig. 2 is a section of the Same on the line 2 2, Fig. 1

Fig. 3 is a section on the line 3 3, Fi Fig. 4 is a section on the line 4 4, Fi F ig. 5 shows a modified detail;

Fig. 6 shows in perspective the hasp; and

Fig.`7 shows in perspective the pivoted dog of the lock.

Referring more particularly to the drawings, 1 is a sheet metal casing having therein two parallel guide-posts 2 2, upon which is slidingly mounted a bolt 3. This bolt has two upper ears 4 4 and two lower ears 5 5 which surround the posts 2 2 respectively so as to provide two upper and two lower sliding engagements with said posts, guiding said bolt. The posts 2 2 are provided with shoulders 6 G below which the lower ears always extend. Between these shoulders and the lower surfaces of the ears 4 4 are two springs 7 7. These springs surround the guide-posts 2 2 and since they engage the lower surfaces of the upper ears 4 4 tend to move the bolt upward and hold the upper ears in contact with the roof of the casing. The shoulders 6 6 are preferably somewhat above the upper surfaces Specification of Letters Patent.

in the bolt and is pivoted to the bolt between the planes of said upper and lower engage- .'ments, by a pivot pin 18 rigidly secured to the dog and entering a hole in the bolt. In

Lorder to hold the dog in either of its positions when moved thereto, I provide a spring detent 15 which is mounted upon the guideposts 2 2 and is provided with a downward projection 16 which engages a lateral stud 14 secured to t-he pivoted dog. As the dog is oscillated in one direction or the other 'by the key, the stud 14 engages the projection 16,v forcing it upward so as to permit the stud 14 to pass from one side to the other of the projection 16.

The pivoted dog is provided at its upper end with an opening 17 and adapted to receive the bit of the key so that when the key is placed upon the pin 9 and turned in one direction or the other the dog 11 is oscillated in a correspondingv manner. mouth of this opening is curved' on both sides so as to present surfaces on which the bit of the key makes tangential engagements.

In order that the pivoted member 11 may act to dog the bolt, the casing is provided with an abutment which is in line with an extension 18 on the lower end of the dog when the dog is in one position and out of alinement therewith when the dog is in the other position. This abutment is preferably the flat inner surface of the bottom of the casing, which bottom has an opening 19 formed therein so that while the abutment is in line with the extension 18 when the dog is in one position, it does not extend so far as to be in line with it when the dog is in the other position.

If desired, the abutment can be formed by bending upward a tongue 20 cut from the bottom of the casing, as shown in Fig. 5. This tongue stands in the downward path of the extension 18 when the dog is in one The l position but is out of alinement therewith when the dog is in theother position. Vhen this latter construction is used, however, the casing has to be alittle deeper than when the construction shown in Figs. l to d is employed.

Vhen the extension 18 is out oi alinement with the abutment, pressure upon the pushbutton 8 moves the bolt downwardly so as to release the hasp 2l in the ordinary manner, the extension 18 moving through the opening 18 or into the space adjacent to the lug 20.A Y y V The four-point guidance of the boltV secured by the four ears 4 4 and'- is of great. advantage in that it produces an easy non-binding action, the guiding of the bolt being secured independently of Vthe pushbutton. The presence of the pivoted dog affords a simple and effective means for dogging the bolt when it is desired to lool: the bag by means Aof a key.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

l. In a bag lock, the combination of a casing, two parallel guide-posts therein having shoulders thereon, a bolt having two upper and two lower sliding engagements with said posts guiding said bolt thereon, said lower engagements extending below said shoulders, springs surrounding said posts between said shoulders and said upper engagements, and key-actuated means for doggingV said bolt.

2. In a bag lock, the combination of a casing, two parallel guide-posts therein having shoulders thereon, a bolt having sliding engagements with said posts guiding said bolt thereon, springs surrounding said posts between said shoulders and the upper portion of said bolt, a key-actuated dog pivoted to said bolt and provided with an extension, said casing having an abutment which is in line with said extension when said dog is in one position and is out of alinement there# with when said dog is in its other position, and a detent for holding said dog in either position.

3. In a bag lock, the combination of a casing, two parallel guide-posts therein having shoulders thereon, a bolt having sliding engagements with said posts giiiding said bolt lower sliding engagements with thereon, springs surrounding said posts between said shoulders and the upper portion of saidvbolt, dog pivoted to said bolt and provided with an extension, said easing having an abutment which is in line with said extension when said dog is in one position, and is out of alinement therewith when said dog is in its other position, and a detent for holding said dog in either position, said detent consisting of a spring member carried by said guide-posts, said spring member having a downward extension and said dog having a lateral projection adapted to engage said spring member on either side or" said downward extension.

a. in a bag lock, the combination of a casing, two parallel guide-posts therein having shoulders, a bolt having two upper andntwo lower sliding engagements with said posts guidingsaid bolt thereon, lower engagements extending below said shoulders, springs surrounding said posts between said shoulders and said upper engagements, a key-actuated dog pivoted to said bolt between the planes of said upper and lower engagements and provided with a downward extension, said casing having an abutment which is in line j with said extension when said dog is in one position and is out of alinement therewith when said dog is in its other position, and a. detent for said dog.

5, In a bag lock, the combination of a casing, two parallel guide-posts therein having shoulders, a bolt having two upper and two said posts guiding said bolt thereon, lower engagements extending below said shoulders, springs surrounding said posts'b'etween said shoulders and said upper engagements, a keyactuated dog pivoted to said bolt between the planes of said upper and lower engageyments and provided 'with a downward extension, said casing having an abutment which is in line with said extension when saiddog is in one position and is out of alinement therewith when said dog is in its other position, and a detent for said dog consisting of a spring member carried by said guide-posts and located below said lower engagements, said spring member having a downward projection and said dog having a lateral projection adapted to engage said spring member on either side Vof said downward projection.
